GUARD FOR ADZES Filed NOV. 15, 1930 INVENTOR. j/en Ty O LYZl/QJZPQ ATTORNEY 7 Patented June 9, 1931 HENRY Q. $WA1 TN, OEI-IATTIESBURG,MISSISSIPPI I r GUARD ron AnzEs application filed. November 15, 1930.Serial no 195,966.

The object of the invention is to provide a device adapted forattachment to the conventional adze whereby the workman will be vprevented from cutting his leg or foot in the use of the tool in theevent of the latter slipping as is frequently the case; to provide aguard which may be readily attached to the 7 conventional adze andspaced the desired distance from the blade; to provide a device of 1this character which may be readily adjusted to maintain itsrelationwith respect to the illustrated in the accompanying drawings,

wherein:

Figure 1 is a top plane view of the conventional adze with the inventionapplied in operative position thereon.

Figures 2 and 3 are respectively end and side elevations of thestructure shown in Figure 1. v 1 Figure 4 is a sectional view on theplane indicated by the line 4.-4 of Figure 1.

lhe conventional adze has the handle attaching eye formed in an upwardextension' 11 and it is to this latter that the guard constituting theinvention is attached. The

, guard proper consists preferably of a metal 5 rod bent to provide thecutting edge shielding portion 12 and the legs 14, the latter followingthe side edges of the blade of the adze 7 and the former the cuttingedge thereof. The legs are offset inwardly back of the blade portion ofthe tool, as indicated at 15, and

these offset portions are threaded, being eX- tended through eyes formedin cross-heads 16 and 17 which are recessed as indicated at 18 toprovide seats in which the extension 11 rests. Nuts 19 threaded on theoffset portions engage the cross-heads on opposite faces and thus serveto bring them in clamping relation with the extension 11. Q

7 Set-screws 20 and 21 are threaded centrally through the cross-heads 16and 17 respectively and engaged in countersinks 22 formedin the outersurfaces of the end wallsofthe extensionll. While the clamping relationof the crossheads on the extension 11 may be generally relied uponitomaintain thedesi'red position. ofthe guard, the set-screws 20 and 21constitute'means for positively insuring its position, since with themset in the countersinl;s,the cross-heads may not slide up or down theextension. I p I The: nuts 19 while constituting means for effecting theclamping function of the crossheads'with the extension 11 alsoconstitute means for adjusting the guard proper so that the shieldingportion 12will be disposed in proper relationto the cutting edge of thetool and as the latter wears and is sharpened the guard may be adjustedbackwar'dly tomain tain its proper relative position with refer--' enceto the cutting edge by, backing off those nuts 19which. engage thecross-head 16 and cross-head 17.

Pr eferably the extension ll is provided with series ofcounter-'sinksf22 on the end screwing forward the nuts which engage thevent its penetrationinto the leg or foot of the workman.

=The invention having what is claimed as new and useful is:

1. In combination withan adze, a guard laterally spaced from butpositioned to parallel the cuttingjedge of'the'latter and prevent itspenetration into the limb of the user.

I 2. In cornbination'with anad ze, a guard 9 removably attached to theadze andliaving a cutting .edge fshielding portion arranged in a spacedrelationlaterally to the cutting edge oftheadzep 3. In combination withan adze, a guard atbeen .described,

tachable to the same and having a cutting edge shielding portionparallelling but laterally spaced from the cutting edge of its blade,said guard being adjustable to maintain the desired relation of theshielding portion and the cutting edge of the adze as the latter isreduced by sharpening.

4. In combination with an adze, a guard attachable to the latter inlaterally spaced relation to the blade thereof and having a cutting edgeshielding portion, the guard being adjustable toward and away from theadze blade.

5. In combination with an adze, a guard attachable to the latter inlaterally spaced relation tothe blade thereof and having acutting edgeshielding portion, the guard being adjustable toward and away from theadze blade and adjustable longitudinally of the blade.

6. Incombination with an adze, a guard attachable to the latter inlaterally spaced relation to the blade thereof and having a cutting edgeshielding portion, the guard being adjustable toward and away from theadze blade and rearwardly to compensate for reduction in the length ofthe blade due to sharpening.

7. In'combination with an adze, a guard having a cutting edge shieldingportion and connected legs, and cross-heads spanning the eye portion ofthe adze, said legs extending through the cross-heads and the latterbeing clamped onthe eye portion.

8. In combination with an adze, a guard having a cutting edge shieldingportion'and connected legs, and crossheads spanning the eye portion ofthe adze, said legs extending through the cross-heads and the latterbeing clamped on the eye portion, and set-screws passing throughtheoross-heads and bearing against the end Walls of the eye portions.

9. In combination with an adze, a guard having a cutting edge shieldingportion and connected legs, cross-heads spanning the eye portion of theadze,the legs extendingthrough said cross-heads and being exteriorlythreaded in the region thereof, and nuts carried on said threadedportions and bearing against opposite faces of the cross-heads.

10. In combination with an adze, a guard having a cutting edge shieldingportion and connected legs, cross-heads spanning the eye portion of theadze on opposite ends, said legs extending through said cross-heads andhung exteriorly threaded in the region thereof, nuts carried on thethreaded portions of the legs and bearing against opposite faces of thecross-heads, and-set-screws passing centrally through the cross-headsand bearing upon the eye portion of the adze.

11. In combination with an adze, a guard having a cutting edge shieldingportion and connected legs, cross-heads spanning the eye portionof theadze on opposite ends, said legs ture.
